[Editor's note: this simply ALWAYS will be true, so is of no use. PHP will convert your var to
a number, even if it is, let's say, "abc"

This seems to work just fine for HTTP variables (params passed by GET/POST, which are always
strings):
if( is_int( $id * 1 ) )
echo "Valid";
else
echo "Invalid;";
